LKS1H222MESA

The LKS1H222MESA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LKS series, optimized for audio equipment and general‑purpose circuits where a smaller, high‑tone‑quality component is desired. It delivers 2.2 mF capacitance at 50 V in a compact radial, can‑snap‑in package and is RoHS compliant.

Designed for board‑level power smoothing and decoupling in audio and other electronic equipment, the LKS1H222MESA combines compact dimensions with performance characteristics intended to improve tone quality when replacing smaller standard products.

Key Features

• Capacitance & Voltage — 2.2 mF rated capacitance at 50 V for bulk energy storage and smoothing in audio and general‑purpose circuits.
• Package & Mounting — Snap‑in terminal, radial can package for secure PCB mounting and robust mechanical retention.
• Compact Dimensions — Size listed as L: 2 × D: 2.5 cm with seated height up to 2 cm, enabling space‑constrained board designs.
• Temperature Range — Rated for operation from −40°C to +85°C to cover typical consumer and professional audio environments.
• Endurance and Reliability — Specified lifetime of 1000 hours at 85°C with defined endurance criteria for capacitance change, tan δ, and leakage current.
• Ripple Current Capability — Low‑frequency ripple handling of 1.75 A (at 120 Hz) for steady performance under AC stress.
• Leakage Current Specification — After 5 minutes at rated voltage and 20°C, leakage current is specified as not more than 3√CV (μA), where C is capacitance (μF) and V is voltage (V).
• Polarized Design & Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% (±20%).
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Bulk smoothing and power supply decoupling in amplifiers and preamplifiers where replacing smaller capacitors can yield improved tone quality.
• Consumer Electronics — Board‑level power filtering in compact devices that require snap‑in mounting and moderate ripple handling.
• General‑Purpose Power Supplies — Energy storage and smoothing in low‑to‑mid power supply rails operating within −40°C to +85°C.

Unique Advantages

• Compact, Snap‑In Form Factor: Snap‑in radial can enables secure PCB mounting while minimizing occupied board area.
• Audio‑Oriented Performance: Specified for improved tone quality versus smaller standard parts, making it suitable for audio signal chain and power sections.
• Specified Ripple Handling: 1.75 A ripple rating at 120 Hz supports stable operation under AC loading conditions common in power filters.
• Clear Endurance Criteria: 1000 hours at 85°C with defined limits for capacitance change, tan δ and leakage current gives measurable reliability expectations.
• Regulatory Compliance: RoHS compliance supports designs targeting regulated markets and environmental requirements.
